Psychological and brain research on self-monitoring with reference to sensory and perceptual experiences

我们研究了一个人对自己状态变化的自我监控与知觉经验的关系。(1)利用主观消失现象制造主观和物理目标消失两种实验情境，考察目标消失的信息源歧视。当一个目标突然消失时，观察者可以区分主观消失和实际消失。(2)外围视觉对持续运动物体的感知并不一定与早期视觉皮层的刺激加工相对应。(3)高分裂型被试自我监控能力较弱，下视野主观消失较少。在这些发现的基础上，我们认为突然和显著的身体变化的存在可能对成功的自我监控很重要，并且分裂型可能影响感知体验。通过设计与人格研究相结合的心理物理任务，我们表明自我监控的分析是可能的。

We investigated self-monitoring of one's own state change in association with perceptual experience.(1) We used a subjective disappearance phenomenon to create two experimental situations(subjective and physical target disappearances) in order to examine discrimination of the information source about a target disappearance. When a target physically and abruptly disappeared, observers could discriminate subjective disappearances from physical ones.(2) We showed that the perception of constantly moving objects in the peripheral vision does not necessarily correspond to stimulus processing in the early visual cortex.(3) Participants with high schizotypy were assumed to show weak self-monitoring and reported less subjective disappearance in the lower visual field. On the basis of these findings, we suggest that the presence of abrupt and salient physical changes may be important for successful self-monitoring and that schizotypy may influence perceptual experience. By devising psychophysical tasks in combination with personality study, we show that the analysis of self-monitoring is possible.
